@sjvn @webmink @dirkhh @osi @lightweight @larsmb I think RMS does not see the "open source" banner as "anti-copyleft", but rather that it focuses on the wrong thing (commerce and economic efficiency, rather than freedom).
That said, one might not come to the conclusion that copyleft is a force for good if one does not see the objective to be "providing and protecting Software Freedom for users."
